I'll Chime in....$10 for Down Under makes the most sense since it is the only "league" offered by the club during the "dark months" It isn't fighting any other locations for the day, or the notion of 3 places on one night (Monday's have 3 leagues in town).
That being said $10 for leagues isn't that much personally but to others it may be. If it doesn't affect your attendance, do it. If it does, CHANGE it. Simple enough. As for me, I will try to make it to the typical 1-2x year to glow, but its tough with everything else to get out there.
Most importantly, be safe in the dark, you never know where Stiles is hiding.
